Description

Technical Field

[0001] The utility model relates to the technical field of textile machinery, in particular to a sueding machine which is convenient for adjusting the gap. Background Art

[0002] The suede sanding device is mainly used in the subsequent finishing process of the textile process to grind a layer of fluff on the fabric, making the fabric softer and more comfortable. Therefore, the processing process of the suede sanding machine can greatly improve the softness and comfort of the textile fabric, which can directly affect the quality of the fabric. In order to facilitate the adjustment of the distance between the suede sanding rollers, the existing suede sanding machine adjusts the distance between the two suede sanding rollers through a bidirectional screw, thereby facilitating the suede sanding operation for fabrics of different thicknesses.

[0003] For example, a Chinese patent document with the publication number "CN217973707U" discloses a sanding machine that is convenient for collecting wool materials. It is screwed to two opposite threaded ends of a bidirectional screw through two threaded blocks. One end of the sanding roller is rotatably mounted on the threaded block, and the other end is connected to a positioning block. The outer wall of the positioning block is slidably connected to the inner wall of the vertical frame to limit the movement of the two sanding rollers. Then, two driving motors are coaxially fixedly connected to the sanding rollers to drive the two sanding rollers to rotate in opposite directions. A Chinese patent document with the publication number "CN212051977U" discloses a sanding mechanism, in which one end of the sanding roller is threadedly connected to the screw rod through a threaded sleeve, and the other end is slidably connected to the slide rod through a threaded sleeve. The two sanding rollers are respectively connected to motors to drive the sanding rollers to rotate.

[0004] In this way, the sanding roller is supported and fixed only by the bidirectional screw on one side of the sanding roller. When the bidirectional screw rotates to drive the two sanding rollers to move closer to or away from each other, a delay will occur when the other end of the sanding roller away from the bidirectional screw slides accordingly. There may be a situation where the moving distances of the two ends of the sanding roller are inconsistent, resulting in inconsistent pressure between the two sanding rollers, and further resulting in uneven sanding effect of the cloth passing between the two sanding rollers; and a motor is arranged on one end of the sanding roller to drive the sanding roller to rotate, and the motor moves with the sanding roller. When the motor is working, it may vibrate, and the side of the sanding roller provided with the motor may be displaced under the action of the motor, resulting in uneven spacing between the two sanding rollers, further affecting the sanding effect of the cloth. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a sanding machine with an easily adjustable gap to solve the problem of uneven pressure between the two sanding rollers in the above prior art and improve the sanding effect of the cloth.

[0006] In order to solve the above technical problems, the utility model provides a grinding machine which is convenient for adjusting the gap, comprising a support platform with mounting frames on both sides, a grinding mechanism and a width limiting structure are arranged on the two mounting frames, the grinding mechanism and the width limiting structure are staggered, the grinding mechanism comprises two shafts, a grinding roller is fixed on the shafts, a bidirectional screw is vertically arranged in the mounting frame through a bearing, the two bidirectional screws rotate synchronously through a synchronous transmission mechanism, a forward-spinning thread segment and a reverse-spinning thread segment are arranged on the bidirectional screw, and the forward-spinning thread segment and the reverse-spinning thread segment are arranged on the two mounting frames. The thread segments are respectively threadedly connected with moving seats, and the two ends of the shaft rod are respectively connected to the corresponding moving seats through bearings. A bidirectional worm is also vertically arranged in one of the installation frames through a bearing, and the bidirectional worm is provided with a positive spiral tooth segment and a reverse spiral tooth segment, and the positive spiral tooth segment and the reverse spiral tooth segment correspond to the positive thread segment and the reverse thread segment. Worm wheels are provided on the two shaft rods, and the two worm wheels are respectively meshed with the positive spiral tooth segment and the reverse spiral tooth segment, and one end of the bidirectional worm is fixed to the output end of the first rotation drive mechanism.

[0007] Furthermore, the synchronous transmission mechanism includes a synchronous motor and a transmission rod, the transmission rod is rotatably arranged on a frame below the support platform, two first synchronous bevel gears are arranged on the transmission rod, the bottoms of the two bidirectional screws moveably pass through the support platform and are fixed to the second synchronous bevel gears, the two second synchronous bevel gears are respectively meshed with the two first synchronous bevel gears, a driving bevel gear is arranged at the output end of the synchronous motor, and a transmission bevel gear meshed with the driving bevel gear is arranged on the transmission rod.

[0008] Furthermore, the first rotation drive mechanism adopts a reduction motor.

[0009] Furthermore, the width limiting structure includes an adjusting threaded sleeve rotatably arranged on a side wall opposite to the two mounting frames, the inner thread of the adjusting threaded sleeve is provided with an adjusting screw, the end of the adjusting screw close to the grinding roller passes through the limiting plate fixed on the mounting frame, the limiting plate is provided with a limiting rod, and the limiting rod is slidably connected to the mounting frame.

[0010] Furthermore, the limiting rods are provided with two groups and are symmetrically arranged on the limiting plate, and the installation frame is provided with sliding holes that are slidably matched with the limiting rods.

[0011] Furthermore, the limiting plate and the grinding roller are staggered in the horizontal direction.

[0012] The beneficial effects of the utility model are as follows: the support platform is used to support the grinding mechanism and the width limiting structure. The grinding mechanism performs grinding treatment on the fabric through two grinding rollers. The width limiting structure is used to limit the fabric during movement to prevent the fabric from shifting between the two grinding rollers and affecting the grinding effect. A bidirectional screw is vertically arranged in the installation frame through a bearing. The two bidirectional screws rotate synchronously through a synchronous transmission mechanism. The bidirectional screw is provided with a positive thread segment and a reverse thread segment. The two moving seats on the same bidirectional screw move closer to or farther from each other on the bidirectional screw to drive the grinding rollers closer to or farther from each other, so as to adjust the inspection fixture between the two grinding rollers, adapt to the thickness of different fabrics or change the grinding pressure of the grinding roller on the fabric. In this way, the synchronous transmission mechanism enables the two bidirectional screws vertically installed in the two installation frames through the bearings to rotate synchronously, thereby enabling the moving seats on both sides of the grinding roller to move up and down synchronously, ensuring that the moving distances of the two ends of the grinding roller are consistent, thereby ensuring that the gap between the two grinding rollers is uniform, and the grinding pressure of the grinding roller on the fabric is uniform. Worm wheels are arranged on the two shafts, and the worm wheels mesh with the forward spiral tooth segments and reverse spiral tooth segments of the bidirectional worm. When the moving seat moves on the bidirectional screw, the worm wheels roll on the corresponding spiral tooth segments on the worm, so that the worm wheels can still mesh with the spiral teeth after the moving seat moves. The first rotary drive mechanism drives the worm to rotate, which can drive the two worm wheels to rotate in the opposite direction, thereby driving the two grinding rollers to rotate in the opposite direction.

[0013] In summary, the utility model can ensure that the cloth will not deviate between the two sanding rollers when the cloth is sanded by the width limiting structure, thereby ensuring the sanding effect of the cloth; by arranging bidirectional screws on both sides of the sanding roller and making them rotate synchronously by the synchronous transmission mechanism, when adjusting the gap between the two sanding rollers, the moving distances of the two ends of the sanding rollers can be uniform, and the installation stability of the sanding rollers can be ensured, so that the sanding pressure on the cloth is uniform; through the coordinated transmission of the worm and the worm wheel, a first rotating drive mechanism can be used to drive the cloth The two grinding rollers are driven to rotate in opposite directions, and during the displacement of the two grinding rollers driven by the moving seat, the worm wheel can roll on the worm, and the worm wheel is always meshed with the spiral teeth on the worm. The displacement of the moving seat will not affect the rotation of the grinding rollers. The first rotary drive mechanism is not directly connected to the grinding rollers, and the vibration generated when the first rotary drive mechanism is running will not affect the grinding rollers, ensuring that the two grinding rollers will not be displaced when the cloth is sanded after the gap adjustment is completed, thereby ensuring that the sanding pressure between the two sanding rollers is uniform, and improving the sanding effect of the cloth. That is, by adopting the utility model, the cloth is limited so that it will not move, and the sanding pressure between the sanding rollers is uniform, thereby improving the sanding effect of the cloth.

DETAILED DESCRIPTION

[0018] With reference to the accompanying drawings, specific embodiments of the present invention will be described in detail.

[0019] Reference Figure 1 to Figure 2 The utility model provides an embodiment of a shaving machine which is convenient for adjusting the gap.

[0020] A sanding machine that is easy to adjust the gap, including a support table 1 with mounting frames 2 on both sides, a sanding mechanism 3 and a width limiting structure 4 are provided on the two mounting frames 2, the sanding mechanism 3 and the width limiting structure 4 are staggered, the support table 1 is used to support the sanding mechanism 3 and the width limiting structure 4, the sanding mechanism 3 sands the cloth through two sanding rollers 32, and the width limiting structure 4 is used to limit the cloth during movement to prevent the cloth from shifting between the two sanding rollers 32 and affecting the sanding effect.

[0021] The sanding mechanism 3 includes two shafts 31 , on which sanding rollers 32 are fixed, and the shafts 31 support the sanding rollers 32 .

[0022] A bidirectional screw 33 is vertically arranged in the installation frame 2 through a bearing, and the two bidirectional screws 33 rotate synchronously through a synchronous transmission mechanism 5. Specifically, the synchronous transmission mechanism 5 includes a synchronous motor 53 and a transmission rod 56, the transmission rod 56 is rotatably arranged on a frame below the support platform 1, two first synchronous bevel gears 51 are arranged on the transmission rod 56, the bottoms of the two bidirectional screws 33 moveably pass through the support platform 1 and are fixed to the second synchronous bevel gear 52, the two second synchronous bevel gears 52 are respectively meshed with the two first synchronous bevel gears 51, a driving bevel gear 54 is arranged at the output end of the synchronous motor 53, and a transmission bevel gear 55 meshed with the driving bevel gear 54 is arranged on the transmission rod 56. The synchronous motor 53 adopts a reduction motor, and the synchronous motor 53 drives the driving bevel gear 54 to rotate, thereby driving the transmission rod 56 to rotate, and the transmission rod 56 drives the two first synchronous bevel gears 51 to rotate, thereby driving the two second synchronous bevel gears 52 to rotate synchronously, so that the two bidirectional screws 33 can rotate synchronously.

[0023] The bidirectional screw 33 is provided with a forward-spinning thread section 331 and a reverse-spinning thread section 332, and the forward-spinning thread section 331 and the reverse-spinning thread section 332 are respectively threadedly connected with a moving seat 34, and the two ends of the shaft 31 are respectively connected to the corresponding moving seats 34 through bearings. At this time, when the two screws rotate synchronously, the moving seats 34 on the forward-spinning and reverse-spinning spiral sections are moved closer or farther away from each other, driving the two shafts 31 to move closer or farther away from each other, and then driving the two sanding rollers 32 to move closer or farther away from each other, so as to adjust the gap between the two sanding rollers 32, adapt to the thickness of different fabrics or change the sanding pressure of the sanding roller 32 on the fabric.

[0024] A bidirectional worm 35 is vertically arranged in one of the installation frames 2 through a bearing, and the bidirectional worm 35 is provided with a positive spiral tooth segment 351 and a reverse spiral tooth segment 352, and the positive spiral tooth segment 351 and the reverse spiral tooth segment 352 correspond to the positive thread segment 331 and the reverse thread segment 332, and a worm wheel 36 is arranged on the two shafts 31, and the two worm wheels 36 are respectively engaged with the positive spiral tooth segment 351 and the reverse spiral tooth segment 352, and one end of the bidirectional worm 35 is fixed to the output end of the first rotation drive mechanism 37. At this time, when the movable seat 34 drives the shaft 31 to move closer to or farther from each other, the shaft 31 drives the two worm wheels 36 to move closer to or farther from each other. Since the shaft 31 is connected to the movable seat 34 through a bearing, the shaft 31 can rotate relative to the movable seat 34. When the two worm wheels 36 move closer to or farther from each other, the worm wheels 36 roll on the positive spiral tooth segment 351 and the reverse spiral tooth segment 352 of the bidirectional worm 35. When the gap between the two sanding rollers 32 is adjusted, the worm and the two worm wheels 36 are always engaged. When the cloth is sanded, the first rotary motor is started to drive the worm to rotate. The positive spiral tooth segment 351 and the reverse spiral tooth segment 352 on the worm can cooperate with the two worm wheels 36 to drive the two worm wheels 36 to rotate in the opposite direction, thereby driving the two sanding rollers 32 to rotate in the opposite direction. Preferably, the first rotary drive mechanism 37 adopts a reduction motor.

[0025] In some embodiments, the width limiting structure 4 includes an adjusting threaded sleeve 41 rotatably arranged on a side wall opposite to the two mounting frames 2. Preferably, the adjusting threaded sleeve 41 is arranged on the mounting frame 2 through a bearing. The adjusting threaded sleeve 41 is provided with an adjusting screw 42 in the inner thread. Preferably, the end of the adjusting screw 42 away from the sanding roller 32 extends out of the adjusting threaded sleeve 41 and is fixed to a limiting ring to prevent the adjusting screw 42 from falling off the adjusting threaded sleeve 41. The end of the adjusting screw 42 close to the sanding roller 32 passes through the mounting frame 2 and is fixed with a limiting plate 43. The limiting plate 43 is provided with a limiting rod 44, and the limiting rod 44 is slidably connected to the mounting frame 2. Preferably, the limiting rod 44 is provided with two groups and symmetrically arranged on the limiting plate 43, and the mounting frame 2 is provided with a sliding hole 21 that slidably cooperates with the limiting rod 44. In this way, the limit rod 44 is symmetrically arranged on the limit plate 43, so that the force on both sides of the limit plate 43 is uniform, and the adjustment screw 42 and the adjustment threaded sleeve 41 are prevented from getting stuck, thereby ensuring the stability of the structure. Furthermore, the limit plate 43 and the sanding roller 32 are staggered in the horizontal direction. The two limit plates 43 can be arranged on the front side of the feeding direction of the sanding roller 32, so that the cloth can be limited and adjusted before entering the two sanding rollers 32, ensuring that the cloth is in the same position when entering the sanding roller 32. At this time, the adjusting threaded sleeve 41 is rotated. Since the limiting rod 44 on the limiting plate 43 is slidably connected with the mounting frame 2, the limiting plate 43 is stopped from rotating, so that the adjusting screw 42 moves axially in the adjusting threaded sleeve 41, and then drives the limiting plate 43 to move in the axial direction of the adjusting screw 42, so that the gap between the limiting plates 43 on the two mounting frames 2 increases or decreases. The distance between the two limiting plates 43 is consistent with the width of the cloth, and the cloth is limited to prevent it from shifting between the two sanding rollers 32.

[0026] In summary, the present invention can ensure that the cloth will not deviate between the two sanding rollers 32 when the cloth is sanded by the width limiting structure 4, thereby ensuring the sanding effect of the cloth; by arranging the bidirectional screws 33 on both sides of the sanding roller 32, and making them rotate synchronously by the synchronous transmission mechanism 5, when adjusting the gap between the two sanding rollers 32, the moving distances of the two ends of the sanding roller 32 can be uniform, and the installation stability of the sanding roller 32 can be ensured, so that the sanding pressure on the cloth is uniform; through the coordinated transmission of the worm and the worm wheel 36, the two sanding rollers can be driven by a first rotation drive mechanism 37. The shaving rollers 32 rotate in opposite directions, and during the displacement of the two shaving rollers 32 driven by the moving seat 34, the worm wheel 36 can roll on the worm, and the worm wheel 36 is always meshed with the spiral teeth on the worm. The displacement of the moving seat 34 will not affect the rotation of the shaving rollers 32. The first rotary drive mechanism 37 is not directly connected to the shaving rollers 32, and the vibration generated when the first rotary drive mechanism 37 is running will not affect the shaving rollers 32, ensuring that the two shaving rollers 32 will not be displaced when the cloth is shaving after the gap adjustment is completed, thereby ensuring that the shaving pressure between the two shaving rollers 32 is uniform, and improving the shaving effect of the cloth. That is, by adopting the utility model, the cloth is limited so that it will not move, and the shaving pressure between the shaving rollers 32 is uniform, thereby improving the shaving effect of the cloth.
